Related Beal adds to life sciences portfolio with reacquisition of 451 D Street

Major mixed-use development in Boston’s Seaport District builds on neighborhood’s biotech footprint and offers more options for innovative space.

Related Beal today announced that Related Fund Management has purchased 451 D Street located in Boston’s Seaport District. The nine-story development offers more than 477,000 square feet of lab and office space, as well as high end tenant amenities. Related Beal, which previously owned the building before selling it in 2012, plans to invest in 451 D’s infrastructure with an eye toward attracting future life-science tenants.

“The Seaport continues to grow as a hub for innovative companies who are doing groundbreaking research,” said Stephen Faber, executive vice president at Related Beal. “We have seen tremendous interest in our ground-up development at Innovation Square and our lab space at 27 Drydock, and now we’re able to expand our offerings to include 451 D Street. This reacquisition underscores the value we see in this neighborhood now and in the future.”

At 85 percent leased, 451 D Street is home to a variety of tenants that include Alion Science & Technology, RDK Engineers and JPMorgan Chase. Tenants benefit from a range of valuable features designed to enhance employees’ experiences, including a brand-new amenity center with a lounge area, games and conference center; a refreshed on-site café offering breakfast and lunch; a 3,000 square foot on-site fitness center; a new 20,000 square foot on-site child care center; abundant on-site parking and enclosed bike storage.

451 D Street has robust infrastructure making it an ideal candidate for lab utilization, including 11’4″-12’3″ ceiling heights, over 30 watts per square foot power capacity and 200 lbs per square foot floor loads. The building is a Wired Certified Platinum property.

Set in a prime location within one of Boston’s most attractive neighborhoods for technology companies, 451 D tenants enjoy proximity to premier restaurants, housing options, nightlife, shopping, and outdoor spaces such as the popular Lawn on D. The building offers shuttles to North Station and South Station, as well as convenient access to the Silver Line Way MBTA Station, Boston Logan International airport, I-93 and the Mass Pike.
